This topic has been previously addressed, but I am reviving it to see if there is new information.
I am looking for a way to distinguish disc 1 out of a multiple disc set from disc 1 out of a single disc album, in order to format the Tag - Filename string. For the former, I would like to use "Disc n" in the filename, but for the latter, would like the filename without the disc specified.
Some others have handled this situation by simply making sure single disc albums have an empty %discnumber% field, but I'd like to find the proper way to handle it. Is there a meta-method that will evaluate the length of %discnumber% for all tracks of the same album name within the specified MP3tag directory? I was thinking I could combine something like that with an if statement to get the desired behavior.
If there is a better way to handle this situation, could you please point me in the right direction?

"MP3tag does not compare files."
Has this changed?
